FOREPOLING Forepoling, also known as tube umbrella, is an application used to strengthen tunnel roof in broken rock conditions. Drilling system consists of casing tubes which are drilled through the overburden as an umbrella and filled with grouting. Robit® Casing System allows easy driving of the casing tubes into the ground with low torque demand. Robit® Casing Systems mostly used in forepoling are RoX+ 88,9/8, RoX 114,3/10, and RoX 139,7/10. ANCHORING Anchoring is a method where walls with masses of overburden are anchored to the solid rock. Casing tubes are driven through the...

WATER AND THERMAL WELL DRILLING Casing drilling is used in making water and thermal wells in broken overburden conditions. Robit® Casing Systems allow easy driving of the casing tubes into the ground with relatively low torque demand. The casing is left in the ground as a protection pipe of the water or thermal well. Robit® Casing System mostly used in water and thermal well drilling is DTH-RoX+. SITE INVESTIGATION Site investigation is used for an initial evaluation of the site and its suitability for proposed development. Casing tube is driven in the selected depth and the sample is taken...
